TO MOVE on from the horrific story of the near fatal effect on the six human volunteers in the disastrous TGN1412 drug trial, there must now be non-animal alternatives found for drug trials.

TGN1412 was extensively tested on monkeys, using dosages 500 times what was given to the volunteers, with no ill effect to them.

Nearly a third of all new drugs tested on animals with no effect fail in human clinical tests. We must learn from this disaster.
